So I followed the standard calibration for my Max2 by using the paper test at each tower and center. however when I do a test print.(https://www.thingiverse.com/thing:25763) I find that the X-axis and Y-axis (cross and back) are .5mm long and the Z-axis(up) is .5mm short.It seams I remember hearing something about an advanced calibration instructions, but I cant seem to find them. does anyone have a link to the advanced calibration? .5mm might not seam like much, but its enough to really foul up a complicated multi part model.
